This is, hands down, the best tongue scraper on the market. I fist got one from my dentist and now get them from this company. I use this at least once daily. I wear invisiline retainers at night and wake up with a gross coating on my tongue and this is the only thing that makes my mouth feel truly clean. Bacteria on your tongue causes bad breath so also works wonders for anyone who suffers from that. Highly recommend this to anyone and everyone!! (Posted on 2/11/2019)
